EFI-231 fault code
My P1 v70 with the Dream XXI system has a constant fault code throwing the lambda light on "EFI-231 Long term fuel trim part load"
I clear the code, and it may run for a week or two, sometimes it comes back on within hours. Its only on LPG not petrol, I replaced the pcv system a few weeks ago with good hoses as the old ones were plugged with screws and gooing up the sump with moisture. Any Ideas?

The reducer type is not set correctly as it should be MP not Std.
Are the injectors standard or fast? You also need to map the system. This can be roughly done with the modify carb or better still with the engineer key to adjust the full map. The autocal will only get you near the right area to start mapping from. |

I cant get the idle to sit steady, so autocalibration wont work, I had it sat on autocalibration for 5 mins and nothing happened. The status bar hit 75% and went back to 0. Ill change the vap settings tomorrow, How do I know if the injectors are 'fast'?
Autocalibration might have to wait till im on an open road where I can make sure I have a steady 2500 - 3500 rpm. Thanks |
